Association of gene polymorphisms with myocardial infarction in individuals with different lipid profiles

Hyperlipidemia or dyslipidemia is one of the most important risk factors for coronary heart disease. The purpose of the present study was to identify gene polymorphisms for assessment of the genetic risk for myocardial infarction (MI) in individuals with low or high serum concentrations of high- density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, or triglyceride (TG), thereby contributing to the personalized prevention of MI in such individuals. The study population comprised 2682 unrelated Japanese individuals (1796 men, 886 women), including 1113 subjects (869 men, 244 women) with MI and 1569 controls (927 men, 642 women). The genotypes for 164 polymorphisms of 137 candidate genes were determined by a method that combines the polymerase chain reaction and sequence-specific oligonucleotide probes with suspension array technology. Multivariable logistic regression analyses and stepwise forward selection procedures revealed that seven different polymorphisms were significantly (P
